My 2012 Hyundai Sonata wont start but the battery is new and has a charge plus all instruments, lights, etc work. In checked all the relays and they also work. My car was running fine earlier today but when I started installing a backup camera and testing the backup light for wiring in the camera after shutting off the car it wouldn’t start again. This has me thinking it’s a fuse or wiring thing and not a starter problem. I have checked all relevant fuses and all seem fine along with relays in the engine compartment. Any ideas??

Does it crank engine and not start?
Too late but I think you've triggered the alarm system messing with it.
Future or now. Get the aftermarket garbage out if already there it will only render you a pedestrian now or later.

IDK, such things exist that don't touch the car's wiring if you must stick with those type things,

Start with the easiest stuff 1st. Clean the battery terminals and cables and then try to jump the car. You said you were installing a camera so you have the ignition switch on You could have run the battery down. Next get a test light and check out the fuses that way not by looking at them
